System limitations

Learn about limitations on the number of nodes and clusters that can be configured in Exasol.

To ensure maximum performance and efficiency, Exasol operates within an optimal range for the number of active nodes in a configuration. If a deployment or database configuration exceeds the optimal range, system startup is declined to maintain system stability.

For Exasol deployments on hardware or cloud instances, the optimal configuration allows up to 64 nodes in a single cluster.
